Specification of Letters Patent.

Patented July 29,1919

Application filed December 2, 1918. Serial No. 265,011.

To all whom it may concern:

Be it known that 1, JOHN CHRISTOPHER NIonoL, a subject of the King ofGreat Britain, residing at the town of Perth, in the county of Lanark,Province of Ontario, Canada, have invented new and useful Improvementsin Closures for Jars or Recepta-cles, of which the following is aspecifica tion.

The invention relates to improvements in jar closures or the like,described in the present specification and illustrated in the drawingsthat accompany the same.

The invention consists essentially of the novel arrangement andconstruction of parts whereby a Spring member, in combination with acontainer having a flange formed therearound and lugs formed beneath andon said flange, on the side thereof, is adapted to efficiently secure asuitable top or cover thereon, at the same time allowing of thereleasing of said top when desired to remove the contents of thecontainer.

The objects of the invention are to provide simple inexpensive andefficient means whereby the tops or covers of containers may besecurely'held in place, quicklyand easily relieved with the fingers whendesired.

In the drawings, like characters refer to corresponding parts throughoutthe several figures.

Referring to the drawings Figure 1 is an elevation view of a containershowing a spring member in closed position.

Fig. 2 is an elevation view of a container showing the spring member indisengaged position for removing the top. V

Fig. 3 is a view of a modified form of the spring member without thehinged part.

Fig. 4 is a perspective view of the spring member showing details of thehinged part.

Fig. 5 is a top view of the cover showing the spring and lugs holding itin place.

My invention is here shown to apply to a glass jar, only, and it will bereadily understood, however, that it may be applied to receptacles madeof metal or any suitable substances.

1- is a container, here shown as glass. The said container has formedtherearound the flange 2, said flange being at or near the top asdesired. 3 are lugs formed on the side of the container, beneath theflange 2.

' purpose of which will be hereinafter described.

l is the customary top or cover which may be flat and may be providedwith flanges to engage the inside of the container, as desired. The saidtop has centrally formed thereon the teatlike projection and four lugs 5at or near the circumference thereof, two on each side of the spring tohold it in place.

The means I provide for securing the top or cover to the container,consist of a curved member 6 which forms a bridge piece across the topof the container, and presses on the projection 5, and held in place bythe lugs 5.

This spring member is made of a length of steel or metal of any desiredwidth, and is slightly curved upwardly, one end of which is bentdownwardly at 7 and then up- Wardly on the under side of the saidspring, at an acute angle or V shaped form, at 8, thus forming thegripping arms 9 and 10, the latter engaging the under side of flange 2thereby holding the top or cover securely fastened to the container.

The other end of spring 6 is angularly bent at 11 to form the hinge 12.

The arm 9 of the spring is made longer than the arm 10, so as toprovide, at 8, a good hold to disengage the latter from the flange 2.

The hinged ortion 12 of the spring is held in place y the lugs 3,oneplaced below the hinge, and one on each side of the hinged part of thespring on the flange 2.

Awire band 13 is placed around the container between the flange and thelugs 3,. said wire passing through the hinge 12 and serving as a pivotto said hinge, and also holding the hinged portion of the spring securedto the container.

This spring, on account of its curved shape, will exert a greaterpressure than a. straight spring would. The pressure will be centrallydistributed to all parts of the top or cover which will therefore besecurely and firmly held to the container. If a metal container is used,the lugs 3 and the wire 13 can be dispensed with, and the hinged portionsoldered or otherwise fastened to the container.

A modified shape of the spring may be used, if desired, as shown in Fig.3, by making both clamping arms, 9 and 10, alike,

and dispensing with the hinged part 12 and; the Wire 13; both clampingarms, 9 and 10, Would then engage the underside of the flange, and couldalso be easily released with the fingers as mentioned above.

While I have shown and described substantially only one form of theinvention, it is nevertheless to be understood that the design of thecontainer as well as the cover or top, might be modified, and otherchanges be made without departing from the spirit and scope of theinvention.

What Ielaim is:

In a jar closure or the like, in combina tion, a container having aflange formed,

amazes therearo'und, a plurality of lugs on the c0Ii-' tainer andflange, a top, a projection, a curved spring member hingedly securedbetween aforesaid flange and lugs, adapted to press on the saidprojection and held in place by lugs formed at or near the circumferenceof the top, clamping V shaped arms provided at its other end to engagethe under side of said flange, a Wire band placed around the container,under the flange, serving as a pivot to the hinge, and holding springmember in position.

In testimony whereof I have affixed my signature. 7 JOHN CHRISTOPHERNICHOL.
